Can you give a we
I am clearly missing something very obvious but why does this happily
compile:
%cython
cdef extern from "mpfr.h":
ctypedef void* mpfr_t[1]
cdef int mpfr_init(mpfr_t)
cdef int mpfr_clear(mpfr_t)
def testmpfr(double x):
cdef mpfr_t input
mpfr_init(input)
mpfr_clear(input)

Is your function usable?
def mplegp(n,m,x):
V=mpmath.legenp(n,m,x)
return float(V.real)+I*float(V.imag)
sage: time plot(lambda x:mplegp(2.1,0,x).real(),(x,-1,1))

this should do what you want
./sage -sh
python -i file.py

I think he's actually asking about the -i flag. I was just wondering
the same thing.
sage myfile.sage
runs myfile but doesn't return the interactive prompt.
I'm guessing the goal is to run a script and have it end with a sage
prompt and some stuff loaded for a session. sage -i looks for
package
if this is possible .. some of my control theory friends will jump into
sage
is it there?
as far as i know there isn't a direct function for it
